Patented Oct. 14, 1930 UNITED STATES PATENT OFFICE GEORGE R. 'ZELLMER, OF OSHKOSH, WISCONSIN. ASSIGNOR T MORGAN WOODWOBK COMPANY, OF WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE DOOR CONSTRUCTION Application filed June 18,

This invention relates to the manufacture of Wooden doors, the object of the nvention being to provide a door of comparatively few parts, which shall be light in weight, sturdy,

durable, of pleasing appearance, capable of being manufactured on a production basis and of being sold at prices considerablybelow those now obtainable for doors of similar general classification. Specifically the 1n- 1O vention provides a door having flush faces and a hollow interior, with a novel arrangement of structural parts whereby the desired features may be easy of attainment.

The nature, characteristics, features and scope of the invention will be more fully un derstood from the following detailed description which is to be taken in connection with the accompanying drawings forming part hereof, in which:

Fig. 1 is a face view of a door constructed in accordance with the invention and having full length flush panels on either side;

Fig. 2 is a sectional view through the line 2-2 of Fig. 1;

Fig. 3 is a sectional v1ew through the line 33 of Fig. 1;

Fig. 4 represents a modified form of door in which the panels do not extend throughout the length of the door;

Fig. 5 is a sectional view through the line 55 of Fig. 4; and

Fig. 6 shows a modified form of stlle espe' cially suitable for use in the door of the mvention.

In the construction of the door of this invention it is contemplated that the structural elements shall comprise stiles, rails and a pair of face panels. Referring first to the embodiment shown in Figs. 1 to 3, the stiles- 11 are exposed on both sides of the door. The l rails 12 are of lesser thickness than the stiles and may be secured thereto either by glued dowel pins 14 or by mortise and tenon connections 15, de ending upon the width of the rails. To t e frame work thus formed by the stiles and rails, a pair of panels 13, of conventional laminated veneer construction, are secured, by gluing under pressure, to the o posed sides of the rails 12 and to the inner 60 e ges of the stiles 11 which are outwardly 1926. Serial No. 116,778.

beveled. The thickness of the rails will be such that when the panels are set and finished their outer faces will be flush with the exposed faces of the stiles 11.

The inner marginal portions of the stiles and the side edges of the panels are correspondingly cut own, as by sticking, to provide an outward bevel-joint 16. It will be of advantage to have the panels and rails so proportioned that, after the panels have been glued and set, their surfaces shall be slightly above the stiles, in which case their side edges will slightly overlap the joints 16.

In the finishing operation these raised portions of the panels will be sanded down to the planes of the opposed surfaces of the stiles, thus providing a smooth, neat appearing door in which the joints between the panels and stiles are effectively closed and inconspicuous.

It is obvious that with the few number of parts involved the door of the invention may be assembled and completed in a minimum of time. The period of drying after gluing, the cost of labor and material and the amount of handling required for the production of this door are far below the requirements of the manufacture of other types of flush doors now on the market.

In Figs. 4 and 5 I have shown the top and bottom rails 12 of the same thickness as the stiles, with the intermediate rails, of reduced thickness, acting as the panel separating and attaching strips.

In this embodiment, the end rails are beveled as well as the stiles, the joint 16 embracing the four edges of the panels.

In order to provide additional surface for gluing purposes, the stiles may have inwardy projecting tongues 17, upon which the panels will seat, as well as upon the rails as shown in Fig. 6.

Other modifications and alternative arrangements of the frame and panel members will doubtless occur to those skilled in the art. and with the reservation that the foregoing specification is presented for illustrative purposes only and that I contem late and intend to cover all modifications em racing the essence of the invention,

By the expression outwardly beveled as applied to the joints between the panel and stiles is meant that the plane of the (joint mclines away from the center of the oor and 5 that the outward angle between the line of joint, as it enters the door, and a vertical line perpendicular to the door is between zero and ninety degrees and is preferably between thirty and sixty degrees. v m I claim:

1. In a door construction, a rectangular frame portion, and rectangular panels set into the openings in both sides of the frame portion and flush therewith, the abutting edges of the panels and the frame portions being ungrooved and outwardly beveled in such manner as to permit the panels to be moved toward the frame portion into positions flush with the sides thereof after completion of the frame portion to form a permanent connection, said connection being made exclusively along said outwardly beveled joints.

2. In a door construction, a frame portion 5 composed of stiles, and intermediate rails and panels set upon the s ides of said intermediate rails, the edges of the panels and of the adjacent marginal portions of the stiles being cut away to form outwardly extending bevel joints therebetween, at which joints permanent attachment between the frame portion and the panel portion is made.

3. In a paneled door construction, a frame construction and insert panels permanently )5 attached thereto, the attachment of the panels to the frame construction being along outwardly beveled joints by means of glue un-v der pressure.

4. In a door construction a. frame portion 40 and a panel portion, the joining edges of the panel portion and the joining edges of the frame portion being cut away to form outwardly extending bevel joints therebetween, said panels being permanently attached to said frame portion along said bevel joints.

5. The method of making a door having a frame and flush veneer panels, which comprises providing cooperating outwardly beveled surfaces on the edges of the frame and panels, and joining the outwardly beveled surfaces with glue by inserting the panels directly within the frame under pressure.

6. The method of making a door having a frame and flush veneer panels, which comprises provlding cooperating outwardly beveled surfaces on the edges of the frame and panels, joinlng the outwardly beveled surfaces with glue by inserting the panels directly within the frame under pressure, and finishing the panel edges to make them flush Wlth the frame surfaces.

In testimony whereof I have hereunto subscribed my name.

66 I GEORGE R. ZELLMER.
